Yo! Data normalization is like making your database less of a hot mess. Instead of stuffing everything into one giant table, you break it down.

Example: If you’re storing student grades, you wouldn’t repeat the student’s name and class for every grade entry. You’d have a Students table and a Grades table linked by student ID.

But overdoing it can mean more complex queries. For small projects, sometimes a flat table is fine.

Try this: Take a messy Excel sheet and try normalizing it—you’ll see the light real quick haha.
